Procurement Notes

Verify the specific part number against official Selec documentation to confirm the 30A primary rating, 1.5VA burden, and Class 5 accuracy. Ensure compatibility with 50Hz to 60Hz operating frequencies and 720V maximum system voltage requirements before procurement.

Selection Notes

Select this component when a 30A primary current transformation to 5A secondary output is required. Consider the 35mm inner diameter for conductor passage and verify that Class 5 accuracy meets the application's precision needs. Confirm the 1.5VA rated burden aligns with connected load specifications.

Part Context

This model belongs to the TWCT series of tape wound current transformers from Selec. The series offers various primary ratings ranging from 30A to 1600A and different accuracy classes. The D35 designation indicates a 35mm inner diameter, distinguishing it from other variants in the product line.

Replacement Considerations

Cross-reference with other Selec TWCT-T-D35 variants such as the 50/5A or 100/5A models if higher primary ratings are needed. Verify that substitute parts maintain the same 5A secondary output, 1.5VA burden, and Class 5 accuracy specifications.
